Problems solved by technology

[0004] During the shooting process, if the user performs a zoom operation, some shaking will inevitably occur, which will have a certain impact on the clarity of the captured image. In the prior art, zooming is not considered when determining the safe shutter time. The shaking caused by the operation makes the captured image not clear and ideal, which reduces the success rate of shooting

Abstract

The embodiment of the present invention discloses a method and device for adjusting the safety shutter time of a photographing terminal. The method includes: detecting the zoom command that the user acts on the photographing terminal; when the zoom command is detected, obtaining the zoom ratio; according to the The zoom ratio adjusts the safe shutter time of the photographing terminal to the target safe shutter time, so that a clear image can be shot according to the target safe shutter time. The technical solution provided by the embodiment of the present invention not only generates the current safe shutter time of the photographing terminal according to the current ambient light brightness, but also considers the impact of the shaking caused by the user's zoom operation on the safe shutter time when determining the safe shutter time of the photographing terminal Go in, adjust the safe shutter time according to the zoom ratio, and adjust the safe shutter time of the camera terminal to the target safe shutter time, which ensures the clarity of the shot image and improves the success rate of shooting.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photography, and in particular, to a method and device for adjusting a safe shutter time of a photography terminal. Background technique [0002] With the continuous development of electronic technology, digital camera equipment (for example, digital camera or mobile phone with digital camera, etc.) has penetrated into thousands of households, and has become an indispensable tool for everyone to record beautiful natural scenery and engrave the wonderful moments of life. [0003] The safe shutter time represents the slowest shutter time for obtaining a clear image when shooting, that is, once the shutter time is slower than the safe shutter time, it will easily cause blurred images. Generally, the safe shutter time is defined as the reciprocal of the focal length. For example, when shooting with a lens with a focal length of 200mm, to ensure that the captured photos are not blurred, ...
